What's New

You can now change your name and email address under Account Settings in the user menu. Email changes require verification — we send a confirmation link to your new address before switching.

If you registered a dyndns.dk hostname under a different email address, you can now transfer it to your current account by verifying your update password. No admin help needed — just go to DynDNS Hostnames and click "Claim Existing".

The propagation checker now queries all 8 global DNS resolvers in parallel instead of one at a time. Typical check time dropped from 10-40 seconds to about 3 seconds.

All delete actions now show a confirmation dialog before proceeding. Forms across the site have been modernized with Turbo Rails for a smoother experience.

All changes to your domains and hostnames are now logged: IP updates (with client IP), record additions and deletions, admin actions, and PowerDNS sync events. This helps us respond quickly to abuse reports and provides a full history of your DNS configuration.

When creating a new free dyndns.dk hostname, the system now checks for conflicts with existing DNS records (like mail or www). This prevents accidental duplicates that could break email delivery or web access for the dyndns.dk domain.

If you had a hostname on the original dyndns.dk site, your account has been migrated to KyedNS. Sign in with the same email address you used on dyndns.dk — no new registration needed. Your hostnames and settings are already here.

See a full history of all changes to your domains and hostnames under "My Activity" in the user menu. Every IP update, record change, and admin action is logged with timestamps. You can also see recent activity directly on each domain and hostname page.

Free dyndns.dk hostnames that haven't received an IP update in 90 days will get a warning email. After 180 days of inactivity, the hostname is automatically disabled to keep the namespace clean. You can re-enable your hostname at any time by logging in and updating your IP.
